they are hungry
Yep feeding them...they must like alot of food....I mixed the nutes twice the recommended amounts and they're taking that stuff like champs....my soil mix usually lasts about six weeks...these ate it up in four weeks . I'm about to up pot them in 3 1/2 gal. planters...they're still in one gal. They all have five bladed fans now and are 36 days old today .I see you got the same three bladed fans.
Any single blades
Are you feeding em yet?

12 on 1 off then 12 on etc. ?You should try the 12:1 veg light cycle.
